A specification forming part of `Lettera ratentNo. 129,549, dated Jniy 23; 1872.' y

Be it known that I, WILLIAM MnssAU, of

y Atlanta, in the county of Fulton and Stateof Georgia, haveinvented a new and Improved Apparatus for Distilling Pine Wood; and I do hereby declare the following to be a full, clear,

` and exact description thereof, which will enable those skilled` in the art to make anduse the same, reference being had tothe accompanyi ing drawing forming part of this specification,

in which drawing- Figure 1 represents a sectional side view of my distilling apparatus when a sheet-metal retort is used. Fig. 2 is a horizontal section of the superheating-furnace detached.` Fig. 3 is a sectional view of my distilling apparatis when a retort of `briclnwork or clay is use Similar letters indicate corresponding parts. This invention relates to an apparatus which is composedof a retort `made of metal or brick and provided with an inclined bottom, said retort being placed in or on a furnace with lateral serpentine ilues, while the retort is furnished with a perforatedlpipe communicating with a steam generator, and with a super` heater, in combinationlwith suitable pipes, l emanating partly fromthe bottom and` partly from the top part of the retort into coolers, in such a manner that when .the retort is filled with pine wood and superheated steam is admitted the spirit of turpentine contained in said wood is first driven out in a pure or nearly pure state andseparatedfrom the subsequent prod y ucts of distillation, andthen, by raising a re in the furnace oftheretort,the destructive distillaf l tion of the wood is completed, and the'gaseous `f distillation resulting rried olf and separated aining in the retort.` he letter Adesignates a la furnace, f, provided` ormedon both sides from 4the charcoa In` the drawing, retort, whichyis` set :with serpentine fines of y the retort,and` communicating with a comi `:non smoke-stack, so that the products ofcomy bustion are compelled to circulate on the sides gofithe retort, as indicated in Figs. 1 and 3, the

etort shown in* Fig. 1 being made of boiler` on,;` and thatshown in Fig. 3 being built up ofbricks orformed of clay, as will be hereafter more fullyexplained. The bottom of ot exposed to the action of the flame, and it is inclined, so that the liquid products of distillation willind their way to a pipe, a,"emanating from the lowest part of extend two (more or less)`pipes, b, intended to carry off the gaseous "products of distillation. These pipes lead into coolers D, where the gaseous `products are condensed, and whence the condensed liquids escape through pipes t' into a receiver, E. The gases which are not condensed pass off` from the receiver E through a pipe, o, and they are collected in a gasometer, I. The pipe q leads to a receiver, F, and the gaseous products escaping through said pipe are carried from the receiver F- into the cooler Gr, where they partly condense, and whence they pass ofi' through a pipe, i', into a receiver, H. The noncondensed `gases es cape from the receiver H through fa pipe, m,

said retort. From the top part of the retort,

and they are collected in the gasometer Ir-- number of holes. The steam is generated in a boiler, B, and thence it` passes through a `serpentine pipe, S, situated in a furnace, G,

(see Fig. 2,) so that it becomes superheated. The pipe S is made of copper inclosed in a fireproof material, and it connects with the pipe c, which extends into the still, as above stated. By the superheated steam pure spirit of turpentine is driven off fromthe wood and carried through the pipes b into the coolersD, where the same4 condenses, and whence it passes through pipes t' into the receiver E. After the pure spirit of turpentine is driven 0E` thesupply ogsteahinwismstopped and a fire is raised inthe furnace f, the `distillation of `thewood and to reduce the wood to charcoal. This operation is facilitated by the admission of air through pipe g,which extends from the retort, (see Fig. 1,) and which is opened and closed at suitable intervals. The liquid products `resulting from this process, together with a small quantity of gaseous products, pass oli through the pipe a, which connects with the lowest portion of the still. lI he gas which collects in the gasometer may either be conducted under the furnace f and used as fuel, or it may be used for illuminat# ing purposes.

so as to complete tar The retort, instead of being made as shown in Fig. 1, may also be constructed of brick, as shown in Fig. 3, Where A*s represents the retort, surrounded by suitable iiues f', which extend from the furnace f to the smoke-stack. The spirit of turpentine passes ed through pipes b* and coolers D* to a receiver, Et. The bottom of the retort is inclined, and a pipe, dit, carries the liquid products of distillation into a receiver, Fi, Which connects with a cooler, Grit, and whence said products pass iu to a receiver, Ht. A pipe, 0*, connects with the superheater. The furnace f is provided with lateral flues h, to throw jets of heated air into the dame, for the purpose of consuming the smoke.

I am aware that wet steam and superheated steam have been used in the distillation of pine Witnesses:
